It runs either \u003cstrong\u003ebottled CO2\u003c\/strong\u003e through a regulator or a \u003cstrong\u003epropane or natural-gas CO2 generator\u003c\/strong\u003e, and doses in stages to reach and hold the level you set. With the optional Evolution NDIR CO2 analyser it reads the room and works closed-loop; without it, it can be interfaced to an external thermostat or hygrostat – Ecotechnics' entry-level route, with an easy upgrade later.

Topping the room up to a controlled level keeps photosynthesis running through the light period, and a controller stops the two expensive mistakes: wasting gas while extraction pulls it out, and overdosing a sealed room.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottled CO2:\u003c\/strong\u003e fit the regulator to the cylinder and connect its solenoid to the controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCO2 generator:\u003c\/strong\u003e connect the burner to the controller instead – the regulator is not needed\u003c\/li\u003e\n\u003cli\u003eIf you use the analyser, place it centrally at \u003cstrong\u003ecanopy height\u003c\/strong\u003e; a circulation fan near the outlet helps spread the gas\u003c\/li\u003e\n\u003cli\u003eSet the target level and let the day\/night sensor limit dosing to the light period\u003c\/li\u003e\n\u003cli\u003eRun it in a \u003cstrong\u003esealed or low-extraction room\u003c\/strong\u003e – constant extraction removes the CO2 as fast as it is added\u003c\/li\u003e\n\u003cli\u003eFollow Ecotechnics' printed user guide for wiring and set-up\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Ecotechnics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Evolution CO2 Controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl:\u003c\/strong\u003e microprocessor, intelligent multi-stage CO2 dosing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCO2 source:\u003c\/strong\u003e bottled CO2 via regulator, or propane \/ natural-gas CO2 generator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor:\u003c\/strong\u003e optional Evolution solid-state NDIR CO2 analyser (not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e external thermostat \/ hygrostat interface; day\/night light sensor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan control:\u003c\/strong\u003e yes; compatible with the Evolution Digital Fan Speed Controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLanguages:\u003c\/strong\u003e English, French, German, Italian, Spanish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegulator (Regulator Only option):\u003c\/strong\u003e Ecotechnics bottled-CO2 regulator with pressure gauge and solenoid, fixed flow; for Evolution and Unis controllers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 year\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cdiv class=\"hcs-faq\"\u003e\n\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eDo I need the CO2 analyser?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eNot to start.
